When it comes to coffee capsule production, rotary (turntable) and linear (straight-line) filling and sealing machines are the two most common types of automated equipment. Their differences mainly lie in design structure, production efficiency, space requirements, application scenarios, and cost. Below is a detailed comparison to help you choose the right machine for your business.
1. Structure Design
- Rotary Machine: Uses a circular turntable design, where capsules move through different stations in a rotating motion. The process includes cup dropping, filling, nitrogen flushing, sealing, and discharge, all happening step by step in a compact structure.
- Linear Machine: Uses a straight-line conveyor system, where capsules move in a linear path. Multiple lanes allow simultaneous operations, significantly increasing production capacity.
2. Production Efficiency
- Rotary Machine: Suitable for small to medium-scale production, typically 30-120 cups per minute. The processing speed is moderate as each cup is handled sequentially.
- Linear Machine: Ideal for high-volume production, capable of processing 200-400 cups per minute. Multi-lane designs allow multiple capsules to be filled and sealed simultaneously, significantly increasing output.
3. Space Requirements
- Rotary Machine: Compact and space-efficient, making it ideal for small factories or workshops with limited space.
- Linear Machine: Requires a larger footprint, as it operates on a long conveyor belt system, best suited for large production facilities.
4. Cost & Investment
- Rotary Machine: Lower cost, simpler structure, and fewer working stations make it a cost-effective solution for small-scale businesses.
- Linear Machine: Higher initial investment, but greater efficiency and lower per-unit production costs, making it a better choice for high-volume manufacturers.
Conclusion: Which Coffee Capsule Machine Should You Choose?
- If your production needs range from 30-120 cups per minute, and you have limited space and a moderate budget, a rotary coffee capsule filling and sealing machine is the best choice.
- If you require 200+ cups per minute and have a large production facility, a linear coffee capsule filling and sealing machine is ideal for maximizing efficiency and reducing per-unit costs.
